For "a cup of tea", we have "two cups of tea",
then how about students? If I have 24 students, which one I should say? "Two dozen of students or two dozens of students"?

Thanks very much!
Use "dozen" just like "thousand".

I have two dozen students.

I have dozens of students. (probably more than two dozen)

You see the similarity?

I have two thousand students.

I have thousands of students. (probably more then two thousand)
Students: We have free audio pronunciation exercises.
Somehow, counting people by unit of "dozen" seems fascinating to me. Doughnuts and eggs are what I am familair with. Emotion: smile
Thank you very much!!!!!! I got it!

We can never add "s" to dozen if there's no "of" after.

I got two dozen students this year.

I got dozens of students this year.
